400w HPS

Discussion in 'Lighting' started by Chamonix, Aug 28, 2018.

  1. I found someone selling a working, 400w HPS with wing and a remote ballast for 20$.

    Is there anything I should look for when purchasing.

    Thats why I would be going to his house to see it working. No shady walmart HPS for me.

    I meant function wise. I doubt moving a super hot HPS is advisable so I cant run it too long. As an aside what is the best way to move something like that.

  4. If I were to go back to hps I’d make sure the light also ran MH bulbs for veg

  6. The bulb gets hot really fast but also cools down really fast. As long as the ballast is in a steel case you could transport it right away after a whole day of running. The case would not likely be any hotter than 80 - 100F so wouldn't even melt a plastic bag much less set fire to anything. I have 4 - 400s and a couple of 1000W magnetics and have used them for almost 20 years. Most are a lot older than that. Only once had to replace the capacitor in one when it failed to fire a good bulb.

    Not even a case on three of them. :) Price was right. Free!

    This one is being used right now to power a 16 yo Hortilux conversion bulb that gives me MH light off an HPS ballast. Was using a 7200K MH PlantMax bulb off my 400w MH ballast but it doesn't seem to grow plants worth a damn and it's nearly brand new. Hoping the Hortilux lasts until I can get a decent MH bulb to run off the MH. Doesn't have to be Hortilux but has to be better than this PlantMax POS.
